When you decant, pronounced "dee-CANT," something by slowly pouring it from one bottle to another, you may feel a little bit like a mad scientist or an alchemist. That image would be appropriate, since early on decant was used by alchemists to describe the process of separating a liquid from a sediment by careful pouring. Today, wine lovers do just that — decanting wine to avoid any solid bits — but pouring any liquid can be described as decanting.
